How to do a `float: left` with no wrapping?

I have a container box1 that has a certain width (which might change depending on its content). That box contains box2 which has a fixed width (it could be an icon). Next to box2, I have box3 with some text. I want the text to use all the space available to the right of box2. With the HTML pasted below, you get:

Short text

So far so good. If the text gets longer, it doesn't wrap around box2 (which is what I want), however, it doesn't make box1 grow, which is my problem. You'll tell me "hey, if you made box3 a position: absolute, how could you expect it to make box1 grow?". Well, I don't but then, how can I get box3 to show next to box2, use all the horizontal space available, and make box1 grow if necessary? (Do I need to say that I'd like this work on IE6 onward, and to avoid using a table?)

You need box 3 to be a block level element, so use display:block and then toss in an overflow:hidden in conjunction with float-ing box 2:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
        <style type="text/css">
            #box1 {  }
            #box2 { float:left; }
            #box3 { display:block;overflow:hidden; }

            /* Styling */
            #box1 { background: #ddd; padding: 1em 0.5em; width: 20em }
            #box2 { background: #999; padding: .5em; }
            #box3 { background: #bbb; padding: .5em; }
            body  { font-family: sans-serif }

        </style>
        <script type="text/javascript">
        </script>
        <title>How to do a `float: left` with no wrapping?</title>
    </head>
    <body>
        <div id="box1">
            <span id="box2">2</span>
            <span id="box3">3<br />3<br />3<br />3<br />3<br />3<br />3<br />3<br />3<br />3<br />3<br />3<br /></span>
        </div>
    </body>
</html>

Amazing all the things overflow:hidden can do :D
